A very concise synthesis of a potent KDR kinase inhibitor 1 is described. The synthesis features an exceedingly efficient one-pot preparation of the aminothiazole 6 followed by Pd–Xantphos catalyzed cross-coupling with chloropyridine aldehyde 11. Reductive amination of the resulting aldehyde 10 with the piperazine fragment 9 afforded the final product.
